A tank having a capacity of 4096 m3 is used by 4 families. If each family uses 4 buckets of water every day and the volume of the bucket is 16 m3 , then the water in the tank will last for ___ days.
16
A family uses 4 buckets of water,
Volume of each bucket = 16 m3.
∴ The total amount of water used by each family per day =64 m3.
and everyday consumption of water by 4 families =64×4=256 m3
∵ Capacity of tank = 4096 m3
∴ Number of days the water will last =4096256=16
Hence, the water in the tank will last for 16 days.
